But this :arrangement has been found to beobjectionaoie particoiziiiy iniough Water, Where the boat pitches, aswhen time boat tails :from :i Wave the Water is piisiie to each side bythe keei and the presence et a tiered cert over the pipe pie 'vents oconstant stippiy oi' Writer 'to the intake pipe.

Titia' has become ,such o,sei'ious diiicuity iocoiities nem? rough water that the ceiitfifugaipump now used oo bott exi-- gilles isfaiiuigf into disfaimr for themason of the usuaiiy iiicomstant the piange? pump is taking' its "piace,s he Latte? style of pump has the disadvantage of robbing the engine ofa. great deut more power wiliie the centiifugo pump is more desirable inevery wey but iequii'es :i constent suppiy of Witter. faim, therefore,to utilize a ceniii'ugai pump and to ossliie :i constant supply ofwzitei" tl'nfougii the intake,

my intake pipe being of such construction' etici so iocztted as toove-:come the diiiicuitics heretofore experienced and give a constantsuppiy in @rough Witte? :moi in ieversing.

in Jigiue l of the drawing have siiown zt boat in outline with myinvention applied thereto. Fig. 2 is a deteii View.

n In this drawing the boat of any oifiineiy ci impiovefjt constructionis shown at A, the propeller at B, the iraficie'm at Chthe engine at MyWater intake is o pipe out diogonaliy ind projecting thz'ough the imiwater supply 1 mi;

et' the host siightiy, being threaded at iuviilg nuts Gr, G, on saidthieuded wirt and. adapted to clamp the pipe in place. The diagonal faceoi the pipe is tc the front and has si. screen arranged on open end. iinoperation it Works eqiiniiy Weil in going 'forward or back its w'ci'ci.Going forward under ordinary conditions the water 1s easily forced in bythe movement of the boat. in rough Water the pitching oi.' the boatgives the open foce of the intake exactly the opposite direction tekenby the Weiter s0 that the pi'oi'o'pt entrance of the latter foliows. n,coing backward, the propeller tends to force the water toward the bowoi the toont and the ioliid surce of the pipe divides this euiiefntiiatmaiiy and" so easily that, for the moment, it tends to iose its,immediate direc `timo and surges :i1-mind and into the 'pipe ami is inthat moment drawn in.

I have found in practice that myimpi'ovc ment will furnish a constantsupply of Water under oil-conditions and that this is not true oi anyintake of which I have knowiedg'e. I

The screen is a most important factor in securing the liest results asby the use of it a more perfect supply of Water is secured, he screeiiassuring an intake of Weiter pract tical V iiiiiioi'm throughout thearea of the ,in combination in famotof boat having a pump for waitercirculation, am Hit-Like pipe of uniform diameter throughout, its lowerend projectie@ through the hull of the boot having its fece out oli" atan angle and cned, the inclined aart facing the bow :md time remindedpart mcing the stern, substantioiiy as deeciibed.
